Key questions for comprehending arc crust formation are: (1) What is the nature of the crust and mantle in the region prior to the beginning of subduction? (2) How does subduction initiate and initial arc crust form? (3) What are the spatial changes of arc magma and crust composition of the entire arc? (4) How do the middle arc crust evolve? This session aimed to gather a wide range of geophysicists, geologists, geochemists and petrologists who are interested in the nature and evolution of arc crust and how this is modified in collision zones and preserved in continental crust. IODP has Project IBM proposals to drill at the IBM, including three non-riser holes (IBM-1, IBM-2 and IBM-3) and one riser, ultra-deep hole (IBM-4). The total four drillings should result in comprehensive understanding of the arc evolution and continental crust formation. JR drilling at three sites (IBM-1, IBM-2 and IBM-3) is scheduled in 2014 from 31 March to 23 September, six months in total. Ultra-deep drilling (IBM-4) is now in OTF and its drilling will be discussed in the Chikyu workshop in April, 2013. Genesis of continental crust will be tackled from both a land-based study and a sea-based study.
